1) Nexon is a huge company, their profits for 2010 were around 617 million. Combat arms isn't even their biggest game, have you ever heard of Maplestory?
2) Very greedy. Really. The whole point of a corporation is to MAKE MONEY. If they stopped trying to make money, the company would die and their games would fall with them. You don't understand the concept of business obviously.
they make alot more from maplestory then combat arms
